The 31-year-old, on loan from Juventus, has not travelled
with his team-mates to Monday's Serie A game at Genoa.

Talks are continuing over a deal that would take him to
Stamford Bridge and Milan are hopeful of signing Genoa striker Krzysztof
Piatek, to enable Higuain's move to Chelsea.

Genoa's general director Giorgio Perinetti has told Italian
radio a meeting over Poland international Piatek, 23, will take place after
today's game and a conclusion is expected one way or another within 48 hours.

If agreement is reached on the proposed moves, financial
negotiations and medicals are likely to be completed swiftly, allowing both
signings to go through.

Higuain's spell at Milan began well, with the Argentina
international scoring six goals in five games for the 18-time Italian league
champions.
